ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connector suitable for smoothly engaging or disengaging both male and female multipolar connector housings.
2. Description of the Related Art
Briefly explaining an example of this type of connector, referring to
FIGS. 19 and 20
, a male connector housing
2
made of synthetic resin of a connector
1
is covered with a slide cover
3
so that the slide cover can be slid on the male connector housing. A base
4
a
of a lever
4
which is turned depending upon the reciprocation of the slide cover
3
is supported on each of both sides of the upper wall of the slide cover
3
so that the base can be turned via a spindle
3
a
for a point of the lever where force is applied. A halfway portion
4
b
of the lever
4
is fitted to each guide portion (point of application)
5
on both sides of the male connector housing
2
and an end
4
c
of the lever
4
can be fitted to a rib (fitting portion)
8
of a female connector housing
7
made of synthetic resin when both the male and female connector housings
2
and
7
are engaged.
As shown in
FIG. 20
, the slide cover
3
is formed in the size of a rectangular cylinder for covering the male connector housing
2
and an extended portion
3
b
for covering each of both sides of the male connector housing
2
is protruded from each side wall. Hereby, the center on the front side of each of the upper and lower walls of the slide cover
3
is notched in the shape of a rectangle. (The notched portion in
FIG. 20
is designated by reference numeral
3
c.
)
As shown in
FIG. 19
, a temporarily fitted state in which the lever
4
is tilted between a protrusion
5
a
of the guide portion
5
of the male connector housing
2
and a tapered surface
6
a
of a lever extruding portion
6
is equivalent to a state waiting for engagement of the male connector housing
2
in the slide cover
3
, when the slide cover
3
inside which the male connector housing
2
is temporarily fitted is extruded inside a hood
7
a
of the female connector housing
7
from the above state, the end of the lever
4
comes in contact with a protrusion
8
a
for supporting a lever of the rib
8
of the hood
7
a
of the female connector housing
7
and the lever
4
begins to turn, and when the slide cover
3
is further extruded in an engaged direction, the male connector housing
2
is pulled inside the hood
7
a
of the female connector housing
7
by the action of the lever
4
(leverage with the spindle
3
a
for supporting the base
4
a
of the lever
4
so that the base can be turned as a point where force is applied, the protrusion
5
a
of the guide portion
5
of the male connector housing
2
as a point of application and the protrusion
8
a
of the rib
8
of the female connector housing
7
as a fulcrum) and both connector housings
2
and
7
are engaged.
In the above connector
1
according to the related art, a state waiting for engagement of the male connector housing
2
in the slide cover
3
is kept by tilting the lever
4
between the protrusion
5
a
of the guide portion
5
on both sides of the male connector housing
2
and the tapered surface
6
a
of the lever extruding portion
6
, however, as an interval between the guide portion
5
of the male connector housing
2
and the lever extruding portion
6
is large, the leverage of the lever
4
does not function in a range of the play of the lever
4
and the lever is in the range of the play of the lever
4
when both connector housings
2
and
7
are disengaged, it is difficult to disengage both connector housings
2
and
7
by small force.
SUMMARY OF THE INVENTION
The present invention was made to solve the above problem and an object thereof is to provide a connector wherein both male and female connector housings can be readily disengaged using the leverage of a lever which is turned by small force even when both connector housings are disengaged.
In order to achieve the above object, the present invention provides a connector comprising: a male connector housing; a female connector housing; a cover in which one of the male and female connector housings is provided so that the one can be reciprocated, being slid; and a lever which is turned depending upon the reciprocation of the one connector housing, a base of the lever being supported by the cover so that the lever can be turned, a halfway portion of the lever being linked with a point of application of the one connector housing and an end of the lever being fitted to a fitting portion of the other connector housing when the both connector housings are engaged, wherein a lever extruding portion to which the halfway portion of the lever is touched in a state waiting for engagement of the one connector housing is protruded from the one connector housing, and an interval between the lever extruding portion and the point of application is set to be small.
